<9>,<10>,<11>,<12>,<13>,<14>*hh<CR><LF>
Fields
<1>
UTC of position, in the form hhmmss
<2>
Latitude, to the nearest .0001 minute
<3>
N if field <2> is North Latitude
S if field <2> is South Latitude
<4>
Longitude, to the nearest .0001 minute
<5>
E if field <4> is East Longitude
W if field <4> is West Longitude
<6>
GPS quality indicator:
0 = Fix not available or invalid
1 = GPS SPS Mode, fix valid
2 = Differential GPS, SPS Mode, fix valid
3 = GPS PPS Mode, fix valid
4 = Real Time Kinematic (RTK)
5 = Float RTK
6 = Estimated (dead reckoning) Mode
7 = Manual Input Mode
8 = Simulator Mode
When providing data from the WeatherStation instrument’s internal
GPS, the only valid values for the GPS quality indicator are 0, 1, and 2
(if WAAS enabled).
<7>
Number of satellites in use, 0-12
<8>
Horizontal dilution of precision (HDOP)
<9>
Altitude relative to mean-sea-level (geoid), meters (to the nearest
whole meter)
<10>
M
